Convenient because it is available on the local network (so anywhere at school).Locally hosted website (Original direction, decided against later) You can’t put restrictions on how the data is edited in a CSV file (risk of malformed data entry).Requires physical access to the bell system.Requires interaction with system which increases the chance of physical damage.User Interface Bell times on an SD card edited via software such as Excel I came up with a basic design for an improved bell controller (a logic board connected to a relay) and then considered options for the User Interface and the Controller Board. The old Huanui College bell controller was very difficult to program, had limited functionality and it suffered from clock drift (where it becomes more and more inaccurate over time). Conclusions – directly linked to the end point market research and testing results.Market Research – does the end prototype meet user expectations?.
Modifications – changes to the original prototype to improve testing results.Testing – how well does the prototype meet design brief specifications and solve the identified problem?.Production materials – identified materials used in the production process with consideration of such things as safety, availability, aesthetics, practicality and costs.Design brief – specifications for production of the prototype model including diagrams.Opportunity – an identified solution pathway the student will pursue to production of a prototype model.Market Research – what is already available in the marketplace to solve the problem? How is the student improving upon that?.Possible solutions – identification of a number of solutions that could be attempted.Problem – an identified problem the student will attempt to solve.Github of the project (Yes, it is under the MIT license, do what ever you want with it) Info Guide The following goes somewhat in depth into the design process and the choices made, for faster info go here:ĬN Science fair submission (actually good design) It’s goal was to make a new bell controller for my school and has been completely and utterly successful by effectively all measures. This is a summary of the tech going into it. This is a project designed for the 2020 Northland Science Fair by Jasper M-W.
